My weird obsession with tension on stringed intruments

I thought I'd go more in to detail. I've had this odd obsession with the tensile strength of a string for years. It started with guitar than quickly spread to other instruments. If you been following me closely you probably could tell I have a fixation with strings. Six years I was hyped about getting 12 string guitar for Christmas. I could't stop thinking about it. I've tested strings on classical and steel guitar,upright and regular bass,mandolin,violin,cello,autoharp and ukelele.I pretty much tested strings on any stringed intrument I can get my hands on.

Bumping this. It looks like my obsession is getting more notice on here. It started when I loosed the g string on an acoustic guitar and it broke.Must of been an old string. The curiosity might be even go further back,but it took off when I snapped the g string. I always wanted to know how high each string can tune too. It's hard to explain.

Ah, so are you saying you're on the spectrum?

So it isn't trying to know how far you can tighten a string because it serves some other purpose, but simply a fascination with the question of how far you can tighten a string, period.

Both. The purpose is to find out how many notes away is the string from breaking from standard.

My guess would be that there is a large margin between the as-specified note pitch and the tensile breaking point of the string. Say a string is 130 lbs when at pitch. I'd be guessing it has at least a 30% or 40% margin. So add another 30% to 40% to reach the snapping point. Maybe more. Maybe 50%.

Or to put it another way, I'd be really surprised if a string was at 80% of the the way to the breaking point when tuned to pitch.

Of course if the string has that much margin, then tuning it to the breaking point may over-stress the truss rod / neck and they may fail first.

The thicker strings of most stringed intruments are about 30 to 40% of the way. That translate to about eight to twelve notes away from breakage. Thinner ones are 50 to 80%,which is about two to five notes away.
 
I still think the worrisome part of this is the neck. If a string breaks, a string breaks. You spend $5 and put a new one one.

But the neck. I wonder how much a string tension a bass neck can take before it is damaged.

Not trying to give you a new obsession, btw, just thinking out loud :-)
